Smart cities collect data from thousands of IoT-based sensor devices for intelligent application-based services. Centralized cloud servers support application tasks with higher computation resources but introduce network latency. Fog layer-based data centers bring data processing at the edge, but fewer available computation resources and poor task allocation strategy prevent real-time data analysis. In this paper, tasks generated from devices are distributed as high resource and low resource intensity tasks. The novelty of this research lies in deploying a virtual node assigned to each cluster of IoT sensor machines serving a joint application. The node allocates tasks based on the task intensity to either cloud-computing or fog computing resources. The proposed Task Allocation Strategy provides seamless allocation of jobs based on process requirements.

As construction projects are gradually getting larger and focusing on building skyscraper with the development of construction technology and the concentration of population in cities, the choice of the soil sheeting works is very important in terms of securing safety and economic feasibility. Further research is planned on the developed concrete guide-based continuous over lap pile method through the introduction of a system that automates vertical management, continuous improvement and supplementation so that the basement soil sheeting wall can be utilized as a building structure.

With rapid urbanization, the importance of urban warfare is increasing, and it is also required to reflect the characteristics of cities in wargame models. However, in the military's wargame models, the urbanization factor was calculated and used without theoretical basis. In this study, we investigate techniques for estimating the urbanization factor using Fractal dimension theory. The urbanization factor we propose can suggest a logical and valid representative value when used in conjunction with Agent Based Model and other methodologies.

In this study the measures and methodology to evaluate the operational efficiency of ITS systems were developed. And they were applied for the ITS systems deployed in the ITS Model Cities in order to figure out their applicability for the operational efficiency evaluation of similar ITS systems which would be deployed in the future.

작년 7월, 강병근 건국대 건축공학과 명예교수가 제4대 서울시 총괄건축가로 위촉돼 활동 중(임기 2년)이다. 서울시 총괄건축가는 도시와 건축관련 정책, 디자인 등 시의 건축사업 전관을 총괄 기획·조정한다. 강병근 서울시 총괄건축가는 지난 5월 18일 본지와의 인터뷰에서 100년 후 도시가 나아갈 방향을 담은 마스터플랜을 계획하는 것이 급선무라 밝히며 관련 계획을 수립 중이라고 밝혔다. 또한 체계적 시스템의 부재로 인한 아쉬움을 지적하고, 서울건축기본계획 등의 시스템 구축과 공공의 도시공간을 위한 실현 방안 등을 계획·정리 중이라고 밝혔다. 아울러 단순한 행정기획이 아닌 선제계획의 중요성을 강조하며 중앙·지방정부부터 기초단체까지 시티아키텍트, 즉 시티플래너가 있어야 한다고 언급했다.

This study was conducted based on the fact that children in institutions for early childhood education located in cities lack the opportunity to experience nature. Therefore, urban parks are where it is possible to observe nature and natural environment, through which we examined the effects of nature activities on kindergarten children's curiosity and scientific problem-solving ability. The subjects of this study were 5-years old kindergarten children in attending public kindergartens in Cheonan and Asan and 42 children were randomly selected. The pretest and posttest were conducted on curiosity and scientific problem-solving ability before and after nature activities. The results showed that nature activities in urban parks had significant effects on improvement of kindergarten children's curiosity and scientific problem-solving ability (p <.05). Therefore, nature activities in urban parks had positive effects on preference for unknown and exploratory behavior, which are sub-factors of kindergarten children's curiosity. Nature activities also had positive effects on discovery and statement of the problem, creation and application of ideas, and conclusion to problem solving.

While urban regeneration projects are currently under active execution in several old cities in Korea, there are few projects to improve the quality of life of rural communities. Considering the decline of the SOC system, deterioration of housing, and degeneration of economic feasibility, the purpose of this study is to provide solutions to realize an improved economic and social environment of rural communities through an integrated management system for traffic safety and water management systems. Therefore, this research used an Entity-Relationship Diagram to construct an integrated system for traffic safety and water management systems for Chungcheong rural communities. The ERD is prepared by depicting 7 relationships for 13 entities, including traffic accidents and agricultural products, and 26 attributes, including soil moisture and underflow storage. Consequently, it will be possible to set up a decision-making support system that can analyze and evaluate the regeneration index, technology, and management of the systems for Chungcheong rural communities, based on supplier and user perspectives

스마트 시티는 수많은 기기에서 데이터를 수집한다는 점에서 보안적인 관점에서 취약점이 존재한다. 이러한 문제점을 해결하기 위해 블록체인의 감사 가능성, 투명성, 불변성 및 탈중앙화와 같은 특징을 활용하여 스마트 시티의 보안 취약점을 보완하는 연구가 다수 진행되고 있다. 대표적으로 자율 주행 자동차에 블록체인을 적용함으로써 보안 문제를 해결하였다. 이 외에도 다양한 적용 사례가 존재하였으며 스마트 시티에 블록체인이 적용가능함을 확인하였다. 하지만 블록체인을 적용시킴으로써 초기 투자 비용, 분산화로 인한 정책 충돌 등과 같은 문제점이 존재하였다. 향후 해당 문제점을 해결하기 위한 연구가 수행되어야할 것으로 사료된다.

이 글은 미얀마의 고대 도시에서 축조된 방어장벽의 건축물에 나타나는 신앙문화에 관한 연구이며, 여러 고대 도시, 특히 쀼족(Pyu)의 도시였던 베잇따노(Beikthano), 하링(Halin), 떠예킷떠야(Thayehkittaya, Srikshetra) 등지에서 발굴된 유물, 유적을 분석하였다. 이와 함께, 미얀마의 고대 도시에 형성된 전통적 신앙세계를 해명하는데 중점을 두고자 한다. 미얀마에서는 성문, 성벽, 요새, 또는 파고다를 건축할 때에 신앙적 요소가 반드시 개입되었다. 건축물의 축조 토지의 선택에 있어서나 건축물 용도에 따른 재앙의 예방의 목적을 구현하기 위하여 신앙체계가 적용되었다. 특히, 방어 장벽(예를 들어, 성벽, 성문 등)에서 나타나는 불교경전이나 쇠못이 박힌 철판 및 각종 힌두신과 낫(정령)의 조상(彫像)은 그러한 신앙적 차원에서 도입되었던 것이다. 결론적으로 미얀마의 고대 도시에 있어서 방어 장벽의 구조물에서도 전통신앙과 힌두교 및 불교가 혼합된 신앙체계가 엿보이며, 나아가 쀼 왕국에 형성된 여러 고대 도시에서 서로 유사한 물질문화와 신앙체계가 널리 존재하고 있음이 밝혀졌다.

This study aims to identify the impact of organizational culture on the work ability of dental hygienists and to analyze the factors that affect dental hygiene work ability. The survey was conducted from August 1 to August 30, 2022, and involved 193 dental hygienists from U and D cities. The data analysis method was conducted using the SPSS 18.0 software. The analysis revealed that age, work experience, and position were the demographic and sociological characteristics with statistically significant differences in dental hygiene work ability. Relationship-oriented culture (β=0.446), career (β=-0.439), age (β=0.358), position (β=0.280), and work-oriented culture (β=0.167) were the most influential factors in dental hygiene work performance. Therefore, it is necessary to work for an extended period to enhance dental hygiene work capabilities and to cultivate a culture focused on relationships.
